2 way solenoid valves  for the steam as the heating medium heaters, radiators, dryers and textile shaping machine, steam dyeing machines, vacuum tobacco resurgence machine , vegetable drying machines and other equipment for the steam pipe with two Automatic and remote on-off switch, temperature

Automatic control. Solenoid valve used in water or a liquid as the working medium, can be controlled automatically or remotely control the water, oil, liquid working medium off the pipeline. As the valve with rubber seal, so the cleanliness of the working medium greatly reduced, with the open and close rapidly, may

Reliability advantages.
Solenoid valve for the second pilot valve opening solenoid valve, the structure of the main valve and the main valve by the guide component, the main valve with rubber sealed structure. Normal position, the movable iron core sealed pilot valve port, the valve chamber pressure balance, the main valve port closed. When the coil is energized, the electromagnetic force of live

Suction on the movable iron core, the main valve chamber from the pilot valve port leakage media, as well as a pressure difference, the diaphragm or valve cup was quickly hold the main valve port opening, passage of the valve will be presented. When the coil power, the magnetic field disappears, the active core is reset, the closed pilot valve port, the pilot valve and the main valve chamber

Pressure balanced, the valve was closed and.
Features: Fluid pressure range limit is higher, can be any installation (to be customized) but must meet the conditions of fluid pressure. Solenoid valve structure and materials from the different and the difference principle, is divided into six branches subcategories: direct acting diaphragm structure, step by step re-sheet structure, the first

Conduction membrane structure, direct-acting piston structure, step by step direct-acting piston structure, the pilot piston structure.
For the truncated valve, internal leakage is not allowed. After two leaks called leak, that media leaks from the valve to the valve outside. L eakage will result in material losses, environmental pollution, can also cause serious accidents. The explosive, toxic or radioactive media, external

Leakage is allowed, and therefore, the valve must have a reliable sealing performance. Liquid solenoid valve installation and maintenance 1, the installation should pay attention to the arrow on the valve body should be consistent with the medium flow. There can not be installed in direct dripping or splashing water. An electromagnetic valve should be vertically upwards

Loading. 2, the solenoid valve should ensure that the supply voltage is the rated voltage fluctuation range of 15% -10% of normal work. 3, the solenoid valve is installed, the pipe may not have reverse pressure. And the required power for several times, so that proper temperature before officially put into use. 4, the electromagnetic

Valve piping should be thoroughly cleaned before installation. Pass into the media should be free of impurities. Valve pre-installed filters. 5, when the solenoid valve malfunction or cleaning, to ensure the system continues to run, you should install the bypass device. 6, takeover note that the sealing material can not be used in excess

, Such as threaded connections, the receiver must not exceed the length of external thread solenoid valve the effective length of the thread and the external thread at the front half of the pitch chamfer with a file, from the tooth at the beginning of winding thread 2 sealing tape, or an excess of sealing tape or bonding agent debris from entering the solenoid valve

Cavity can cause malfunctions.  2 way solenoid valve
First, according to the pipeline parameter selection solenoid valve: Path specification (ie DN), Interface 1, according to the pipe diameter spot size or flow requirements to determine the diameter (DN) size. 2, the interface m ode, general> DN50 to choose flange interface, ≤ DN50 may be based on use

Households need freedom of choice.
Second, according to the solenoid valve fluid parameters: material, temperature, group 1, corrosive fluids: better to use solenoid valves and corrosion-resistant stainless steel; eating clean fluid: better to use food-grade stainless steel solenoid valve. 2, high-temperature fluids: To select high-resistant

Temperature electrical materials and sealing material of the solenoid valve, but also to select the piston-type structure. 3, the fluid state: Big ranging from a gaseous, liquid or mixed state, especially when ordering sizes greater than DN25 must separate. 4, the fluid viscosity:

Usually 50cSt the following can be arbitrarily chosen, if it exceeds this value, will have to use high viscosity solenoid valve.
Three, according to the parameter selection pressure solenoid valve: principle and structure of varieties 1, no minal pressure: This parameter and other common meaning is the same as the valve is based on nominal pipe to be. 2, working pressure: if the working pressure is low then you must use straight

Action or step direct-action principle; minimum working pressure at 0.04Mpa or more direct-acting, step by step direct-acting, pilot can be selected.
